🌐 What Is Express.js?

Express.js is a fast, minimalist, and flexible web application framework for Node.js that simplifies the process of building server-side applications and RESTful APIs. Developed as part of the Node.js ecosystem, Express provides a robust set of features for routing, middleware management, session handling, and API development, making it one of the most popular frameworks for backend JavaScript development.
Express.js powers modern, scalable, and high-performance applications, and is often used in conjunction with MongoDB, Angular, React, and Node.js (the MERN or MEAN stack) for full-stack web development.
